What explains the faster context switching of goroutines compared to threads?

Faster context switching in goroutines compared to threads is explained by their lightweight nature and implementation features:

• Goroutines are managed by the scheduler within the Go runtime, not the operating system, which reduces overhead for switching.
• Goroutines have a small stack (starting from a few kilobytes) and grow dynamically, unlike OS threads with a fixed large stack, reducing creation and switching costs.
• Context switching between goroutines is faster because it does not require kernel switching and related operations.

Thus, goroutines allow efficient execution of a large number of concurrent tasks with minimal overhead for thread management.
